Abstract (en)

[origin: EP0381541A2] There is disclosed a superconductive magneto-resistive device for detecting an extremely weak magnetic field. In the superconductive magneto-resistive device, plural superconductive pieces are formed apart from each other with a small gap on a non-magnetic substrate, and there are formed films of a conductive or semiconductive material between each pair of the adjacent superconductive pieces on the substrate so as to be in contact with each pair of the adjacent superconductive pieces. Each of the film forms a weak coupling due to the proximity effect between each pair of the adjacent superconductive pieces.
